Pojęcie MVP (Minimum Viable Product) jest jednym z częściej nadużywanych i mylonych w branży IT. Zdarza się, że dwie osoby dyskutujące o zbudowaniu produktu, rozumieją je zupełnie inaczej. W tym artykule przybliżę czym jest MVP, jakie są jego rodzaje oraz czym różni się od koncepcji MMP (Minimum Marketable Product) i POC (Proof Of Concept). Pojęcie MVP spopularyzował Eric Ries w s...

Boom! 💥 Pomimo sezonu urlopowego, już 27-28 sierpnia odbędzie się w Krakowie jedna z pierwszych po przerwie epidemicznej, programistyczna konferencja OFFLINE.

(This article will be split into multiple parts since it would be too long) Writing correct benchmarks is hard, and it's a craft. Benchmarks try to test a piece of code running in isolation which is very hard, and the results will be mainly in milliseconds or even in smaller units of time. Consider how hard it is to measure such timings correctly and filter out the noise and other system components running at the time that might contribute to the benchmark result. Performance Testing APIs or Large s...

Richard July 28th, 2021 Open source was an attractive and exciting idea when we first considered sharing .NET Core on GitHub. At the same time, GitHub was a largely unknown platform for many of us and we had a lot of questions about how everything would work. “What if someone forks the runtime on the first day? Is the project over?”. We knew enough that we should take the time to learn the patterns that developers had already established and also what they expected of us. That said, we also had to host...

AboutPAC-MAN12 min read. What happens when you build a .NET app? What happens the instant you run it? The last time I studied this was when .NET Framework was in its infancy. That was nearly 20 years ago! Things have changed in those two decades: apps are now cross-platform; .NET has lost its "Framework" moniker; and I've lost my hair! This post looks at:what's in a modern .NET 5 (C#) projectwhat's generated when you buildwhat happens when you run it We won't go into a massive amount of detail, but ...

Sam July 9th, 2021 API versioning can help evolving our APIs without changing or breaking the existing API services. URL segment, request header, and query string are three ways to achieve API versioning in ASP.NET Core application. ASP.NET Core OData 8, built upon ASP.NET Core, has the built-in API versioning functionality via route URL prefix template. For instance, the following code configures a version template in the route URL prefix to achieve URL based API versioning: services.AddControllers(...
